Thibaut Courtois has been ruled out of Chelsea's clash with Brighton & Hove Albion this afternoon through injury with Willy Caballero making his Premier League debut for the Blues.

Courtois picked up the knock in training and will miss a league match for the first time this season, adding to Chelsea's injury woes with Danny Drinkwater also not fit enough to make the matchday squad.

After playing 70 minutes on Thursday in a behind-closed-door friendly, Ross Barkley is fit enough to start on the bench as he looks to make his competitive debut for the club.
